I had done the port to mipsel-linux-uclibc gcc for GCC 4.9/5.0/6.0. Maybe I can give some help for you. Let's do the last mile. To do this, I have some questions. Should we port to the upstream LLVM first and port them back to GCC? Maybe some GCC-only files should be targeted directly like gcc/config/ and even configure.tgt. Regards, Jean
